Product details
Overview
1N6289-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 53.2–58.8 V breakdown voltage (VBR), 47.8 V standoff voltage (VWM), 77.0 V clamping voltage at 19.5 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 µs waveform - used in DC power rail and signal line protection for industrial motor drives.
For engineers reviewing the 1N6289-E3/73 datasheet, 1N6289-E3/73 pinout, 1N6289-E3/73 application, or 1N6289-E3/73 equivalent, this part serves as a high-energy, fast-response (≤1 ns), glass-passivated unidirectional TVS for surge immunity per IEC 61000-4-5 in automotive body control modules, industrial PLC I/O terminals, and telecom power supplies.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 47.8 V), but triggers into low-impedance conduction when transient voltage exceeds its 53.2–58.8 V breakdown range. Its 15.4 °C/W junction-to-lead thermal resistance enables reliable energy dissipation during repetitive 10/1000 µs surges up to 0.01% duty cycle.
The 1N6289-E3/73 uses a molded epoxy case (Case Style 1.5KE) with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102, rated for solder dip at 275 °C for 10 s. It is RoHS-compliant (E3 suffix), commercial-grade, and not AEC-Q101 qualified - distinguishing it from HE3-suffix variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 47.8 V - maximum continuous working voltage before leakage exceeds 1 µA; sets safe operating margin below breakdown |
| VC @ IPPM | 77.0 V - clamped voltage seen by protected circuit during 19.5 A 10/1000 µs surge; determines residual stress on downstream ICs |
| PPPM | 1500 W - peak pulse power handling capacity; supports robust protection against lightning-induced transients (IEC 61000-4-5 Level 4) |
| IPPM | 19.5 A - maximum non-repetitive surge current the device safely clamps without degradation |
| TJ max | 175 °C - maximum junction temperature; enables operation in high-ambient environments like engine bay or industrial enclosures |
| RθJL | 15.4 °C/W - low thermal resistance from junction to lead; allows efficient heat transfer to PCB copper pour or heatsink |
Pinout & Package
Package: Case Style 1.5KE - axial-leaded, molded epoxy body (1.0" × 0.285", 25.4 mm × 7.2 mm), UL 94 V-0 rated, with cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-side reference; forms return path during transient clamping |
| Cathode (banded end) | Current exit point during reverse-biased clamping | Connected to protected line (e.g., +12 V rail); conducts surge current to ground when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 µs) | Supports single-event surge immunity up to IEC 61000-4-5 4 kV/2 Ω open-circuit test condition |
| Clamping response time ≤1 ns | Protects nanosecond-scale logic and analog circuits before transient energy reaches vulnerable nodes |
| Low incremental surge resistance | Minimizes voltage overshoot during high-di/dt events, reducing risk of secondary overstress failure |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for lead-free reflow and wave soldering processes |
Applications
| Industrial Motor Drive Power Input | Automotive Body Control Module (BCM) CAN Bus Line |
|---|---|
Use Scenario: Protection of 24 V DC input stage against load dump and inductive switching transients in variable-frequency drives. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between +24 V rail and chassis ground, triggered within 1 ns to clamp surges above 47.8 V.

IC Role / Device Role / Timing Role: Primary overvoltage clamp on regulated 48 V output, coordinated with OVP circuitry to prevent latch-up. Use Value: Absorbs 1500 W transient energy without thermal runaway, enabling compliance with GR-1089-CORE surge immunity requirements. |
Use Scenario: Surge suppression on 12 V mainboard rail feeding microcontrollers and display drivers in smart home hubs. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) standby protector that activates only during >53.2 V transients, avoiding false triggering during brownout recovery. Use Value: Enables fail-safe operation by holding downstream logic supply within 77.0 V clamping limit during 10/1000 µs 1 kV surges per IEC 61000-4-4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-E3/52 | DO-214AA package (SMB), 58.0–64.4 V VBR, 50 V VWM, 93.6 V VC @ 16.0 A, lower PPPM (600 W) | Surface-mount footprint; lower clamping voltage margin and power rating limits use to lower-energy transients | Select when board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 2 (2 kV) |
| 1.5KE56A-E3/54 | Same 1.5KE package, identical VBR/VWM/VC specs, but supplied in 13" paper tape/reel (1400 pcs) vs. 7" reel (750 pcs) for 1N6289-E3/73 | No functional difference; identical electrical and thermal performance; differs only in packaging format and reel size | Choose for automated SMT assembly requiring standard 13" reels; no design or layout change required |
Compared with 1N6289-E3/73, SMBJ58A-E3/52 offers compact SMT integration but sacrifices 60% peak power handling and higher clamping voltage, while 1.5KE56A-E3/54 delivers identical protection performance in a different packaging configuration optimized for high-volume pick-and-place.

FAQ
What is the breakdown voltage range of the 1N6289-E3/73?
The 1N6289-E3/73 has a specified breakdown voltage (VBR) range of 53.2 V to 58.8 V at 1 mA test current, measured per JEDEC standards. This range ensures consistent clamping initiation across production lots and provides design margin for temperature drift (0.103 %/°C coefficient). The 1N6289-E3/73 must be selected based on system operating voltage and required safety margin above VWM.
Is the 1N6289-E3/73 suitable for automotive applications requiring AEC-Q101 qualification?
No, the 1N6289-E3/73 is a commercial-grade part with E3 suffix and is not AEC-Q101 qualified. For automotive applications requiring qualification, Vishay offers the HE3-suffix variant (e.g., 1.5KE56AHE3_B), which meets AEC-Q101 stress testing. The 1N6289-E3/73 may be used in non-safety-critical automotive subsystems only after full system-level validation.
What is the maximum clamping voltage of the 1N6289-E3/73 under surge conditions?
The 1N6289-E3/73 exhibits a maximum clamping voltage (VC) of 77.0 V at its rated peak pulse current (IPPM) of 19.5 A, tested with a 10/1000 µs waveform. This value represents the worst-case voltage imposed on protected circuitry during a full-power transient event and must be verified against downstream component absolute maximum ratings in the final design.
How does the 1N6289-E3/73 differ from the 1.5KE56A-E3/54?
The 1N6289-E3/73 and 1.5KE56A-E3/54 are electrically and thermally identical parts - same VBR, VWM, VC, PPPM, and package - differing only in packaging format: 1N6289-E3/73 ships in a 7" diameter reel (750 pcs), while 1.5KE56A-E3/54 uses a 13" reel (1400 pcs). Both share the same RoHS-compliant E3 plating and commercial-grade specification.
What is the thermal resistance from junction to lead for the 1N6289-E3/73?
The 1N6289-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, measured under standard test conditions. This low value enables effective heat transfer from the silicon die to the PCB copper via the axial leads, supporting reliable operation under repetitive surge conditions when mounted with ≥0.375" (9.5 mm) lead length.
